CVE-2026-70496— Search-v2-operator: search-v2-operator: operator clusterrole is cluster-admin equivalent via impersonate, rbac write, csr approve, and manifestwork

Quick assessment

Affected
Red Hat Red Hat Advanced Cluster Management for Kubernetes 2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 search-v2-operator 中发现了一个漏洞。该操作器的 ClusterRole 拥有与集群管理员等效的权限，允许其模拟其他实体、写入基于角色的访问控制（RBAC）配置、批准证书签名请求（CSRs），以及管理 ManifestWork。这些权限超出了操作器正常功能所需的范围，可能导致集群内的权限提升。

Vulnerability Title
Search-v2-operator: search-v2-operator: operator clusterrole is cluster-admin equivalent via impersonate, rbac write, csr approve, and manifestwork
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in search-v2-operator. The operator's ClusterRole has permissions equivalent to a cluster administrator, allowing it to impersonate other entities, write Role-Based Access Control (RBAC) configurations, approve Certificate Signing Requests (CSRs), and manage ManifestWork. This grants excessive privileges beyond what is necessary for the operator's intended function, potentially leading to privilege escalation within the cluster.
